MEANS FOR ATTACHING TOOLS TO THEIR HANDLES.

SPEGEFIGATION forming part of Letters Patent No. 676,984, dated June 25,1901.

Application filed July 9, 1900- Serial No. 23,014. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHANN HOFBAUER, a subject of the Emperor ofAustria-Hungary, and a resident of Vienna, Austria-Hungary, haveinvented certain new and Improved Means for Attaching Tools to TheirHandles, of which the following is a full, clear, and eX- actspecification.

The present invention consists of improved means for attaching tools totheir handles, and more particularly for attaching the blade of a scytheto its snath.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout the several views.

Figure 1 is a perspective view of the attachment; Fig. 2, asectionalplan of the same, and Fig. 3 a perspective View of the blade and snathof a scythe attached.

The device consists, essentially, of a ring I), having riveted thereto abolt with interior head f, on the stem of which bolt a U-shaped wedge cis adapted to slide by means of the slot at, the webs of the saidU-shaped wedge 0 being tapered, as will be seen from Figs. 1 and 3,toward the lower end. The pin or rivet is fast on the ring I), and theheadf of the same lies between the webs of the U- shaped wedge c.

In order to fix the scythe to the snath, the stem g of the scythe-blade,together with the snath a, is passed through the ring I), the wedge clying between the ring and stem g. By gently tapping the upper part ofthe wedge it will be'driven tightly home, thus properly securing thescythe-blade to the snath.

Although the device has been described in connection with a scythe, itwill be obvious that the attachment could be employed in connection witha variety of other tools and implements, and the application istherefore not confined to the scythe.

1 claim as my invention- The combination of a ring to embrace thetool-stem and the tool-handle, a wedge Vertically disposed to the planeof the said ring and adapted to lie between the ring and the handle,said wedge being of U-shaped section, a pin or rivet in the said ringhaving its stem extending through the said wedge and a slot in the backof the wedge to enable the same to move on the said pin in the mannerand for the purpose substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

J OHANN HOFBAUER.
